Hi, I am a student and I am looking for a hybrid stepper motor with no electromagnetic breaks and a minuscule detent torque. Unfortunately, whilst browsing the RS website I was unable to find this information as it is not listed in any of the data sheets.
The application of said motor is for a double pendulum. A motor at the top in the base of the pendulum will theoretically (mostly) smoothly move and exhibit natural pendulum motion whilst also having the opportunity to be activated from electronic input. By turning the motor on for a split second, applying the rotational force on the body and then turning it off again as soon as possible, ideally, the natural motion of the double pendulum will be observed.
